APPARATUS FOR MAFTUPACTURE 01? POSTS AND THE LIKE 0F REINFORCED 1 CONCRETE.

To all whom it may concern:

Be it known that I, RoMEDIUs PANZL, a citizen of the UnitedStates, and a resident of Muskegon. county of Muskegon, and State I of'Michigan, have invented certain new and useful Apparatus for Manufacture of-Posts to rotting and corroding, ascompared' withwooden, or iron posts, yet their more extensive use was heretofore prevented by the fact, that without reinforcement with metallic rods, they are not safe, being liable to be broken by impact, and that the costs of manufacture of so reinforced concrete, or artificial stone, posts as heretofore pursued, renders the product too expensive.

The object of my invention is to provide an apparatus, by which reinforced concrete posts may be produced rapidly and cheaply, and the posts also provided with means for attaching fence wires thereto, so that the wires, or fence bars, can be secured thereto.

The apparatus for this purpose, constructed according to my invention, consists substantially of a form, a base and a standard for setting up the form in position, of meansfor setting up and maintaining the reinforcing rods in their place inthe form, and of means for compacting the material filled into the form..

An apparatus embodying my invention is shown in the accompanying drawing, where- '1n a V Figure 1 is an elevation, partly in sec tional view of the apparatus; Fig. 2 is a cross-sectional view on line 2-2 in Fig. 1, and a plan viewof the base; Fig. '8 1s a cross-sectional view on line 3 3 in Fig. 1, a

. The post form 141 may be round, as shown in the drawing, or polygonal, according to in what shape the posts are to be produced, and is made preferably of two parts, hinged together, as shown in Figs. 1 and 4:, or fitted together as shown in Fig. 7 Tts dimensions and shape of the posts to be produced. Near the upperend of the form an opening is Patented ta 31, ioia.

Application filed February 12, 1915*. Serial No. 7,736.

Fig. 10 is an elevation, partly and shape are determined by the dimensions to whether only one or two rows of eyes for fastening the fence wires are wanted. The slots extendfrom the level of the door opening downward, to apoint at which the lowest loop and eye is to be set in the post,

and, if two. are desired, they may be in llne' with each, other, or placed at an'angle. For

the manufacture of posts without eyes for attaching fence wires thereto, the forms need not-be provided with such a slot, or slots.

The standard 13 is made preferably inte-- gral with the base 12, and preferably so extended, that the pounder 15 maybe movably suspended therefrom in line with the form. For this purpose, the pounder is tied to the end of a rope 27 laid over the block 26, by which the pounder is raised and dropped. The pounder 15 is-used for tamping the concrete material in the, form, and also to assist in maintaining the'reinforcing A recess 18 is made in the base 12, corresponding in shape and dimensions to the shape and dimensions of the form 14, so that the form may be set therein. The upper end of the form 14 is held in vertical position and in alinement with the recess 18 in the base, and with the pounder 15, by the bracket arm 23, made preferably integral with the standmade in the bottom of the recess 18, as

shown in Fig. 11, into which the ends of the reinforcing rods 21 may be set, if it is not desired to have the 'rods U-shaped pairs, as shown in Fig. 2. It should also be understood,.that more or less than four of the reinforcing rods'may be used, if desired. For the manufacture of solid posts it is, however, preferable to have the reinforcing rods bent in U-shape, as shown in the drawings.

The reinforcing rods 21 are longer than v the form, and their upper ends project therefrom, as shown in Fig. 1, engaging in the perforations 22 of the pounder 15, whereby they are constantly maintained in a fixed relative position to the form 14, and to each other.

.The apparatus as thus far described, is suitable for the manufacture of solid posts. If it is desired to make the posts hollow, a

core 24, as shown in Figs. 10 and 11 may be .set in, concentrically into the form, for

which purpose acorresponding recess in the base 12 is provided. This core 24, is also longer than the form 14, and when used, a corresponding perforation is made in the pounder 15, by means of which the core is maintained in its concentric position in the form. It should also be noted, that if the U- shaped form of the reinforcing rods is to be used, the lower end of the core 24 is to be correspondingly recessed.

The manufacture of such posts by means of this apparatus, is proceeded with as follows: The form 14 is set up and fixed in its position, as shown in Fig. 1. Then the reinforcing rods 21 are set in place, the' pounder having been raised out of the way. Then the pounder is slowly let down, while the operator holds the projecting ends of the reinforcing ends in position, so they will enter the perforations 22 in the pounder, as

the latter is let down. Next the door 16 is opened and swungaside, as shown in Fig. 4, and a portion of the material (concrete, or

. artificial stone mixture) of which the post is to be made, is dropped in into the form through the door. This material is dropped in into the form successively, the pounder being used to compact each instalment of the material. When the level of the material reaches the point, at which the first loop (or perforation) is to be made, the pounder is raised above the door, and a loop or tie 28,

rods 21 and so thatthe eye 29, which is to project from the post, lies in the slot 17 as shown'in Fig. 3. If the eyes 29 are to be on two (or more) sides of the post, additional loops 28 are so placed with the eyes in opposite slots, or angularly disposed relatively to each other. The loop is then pushed down by the pounder l5, and pressed into the still soft material of the post. Then the pounder, 15 is again raised above the door, and the next instalment of the material is charged in into the form, and compacted by the pounder, as explained.

' When the level of the material has reached the point, at which the second, or next following tie, or'loop 28 is to be set, the above explained operation is repeated, and the work-is progressively continued, until the level of the door 16 is reached. It will be noted that a notch 17 is made in'the upper edge of the lower half of the door 16, and in the lower edge of the upper half. The object of this is to enable the last loop 28 to be set in, in position, through the upper half of the door 16, the lower half of the door 16 done, the upper half of the door 16 is closed and fastened, and the balance of the material, required to complete the post, is dropped in, in successive instalments through the upper opening of the form and compacted in the same way as heretofore explained. Then the pounder is raised, and the projecting ends of the rods 21 may then be cut off, and the upper end of the post suitably finished, fiat or in the shape of a conus, or a pyramid, or otherwise, as may be desired. If the posts are to be topped by ornamental heads, or by transverse coping, it is preferable to leave the ends of the reinforcing rods 21 project ing therefrom, and to utilize them for connecting thereto the coping, or the heads, etc.

If the posts are to be used for constructing a fence of iron rods, or of piping, it is preferable to provide them with perforations 31, as shown in Figs. 8 and 9. In such a construction, no eyes 29 are formed on the loops or ties 28, and the perforations are made in the posts at the points where the iron rods, or piping, is to. be run therethrough. This is effected by placing in the form 14, at such points, where the perforations are to be, correspondingly dimensioned .having been closed. After this has been cores to lie transversely through, the center bracket arm 23 is opened, and the form with the post within is swung out. It is best to have suitable attachmentsprovided' on the form for swinging it first into a horizontal position, and then away to where the form- (with the post) is to be deposited. Itshould be laid in approximately horizontal position, andthe material in the form allowed to set, whereuponthe form may be opened and the finished and hardened post rolled out. There must be, of course, a sufiicient num ber of the forms-and also of the coresprovided, as the posts should not be removed therefrom until the material has set and sufficiently hardened.
